On Delay-robustness of Extremum Seeking of Nonlinear Static Maps with Small Disturbance
Jianzhong Li, Yang Zhu, Hongye Su
Extremum seeking (ES) is a real-time optimization strategy, thus transmission delays in the feedback loop of ES have big impact on its stability. How big delay that ES control syst…

Critic-Free Policy Iteration for Continuous-Time Zero-Sum Games: A Policy-Space Riccati Approach
Jiacheng Wu, Yang Zhu, Hongye Su
This paper develops a critic-free policy iteration (PI) method for continuous-time linear zero-sum games. The central idea is to characterize the saddle-point policies directly in…

Data-Driven Critic-Free Policy Iteration for Continuous-Time Linear Quadratic Regulation
Jiacheng Wu, Yang Zhu, Hongye Su
For continuous-time linear quadratic regulation with unknown system matrices, data-driven off-policy policy iteration typically estimates the value matrix and the improved feedback…
